displayed or the sensor may not be able to detect an object. Once the ice melts, the
system will return to normal.
■If “Parking Assist Unavailable” is dis-
played on the multi-information display
●Water may be continuo
usly flowing over
the sensor surface, such as in a heavy
rain. When the system determines that it
is normal, the system will return to nor-
mal.
●Initialization may no t have been per-
formed after a battery terminal was dis-
connected and reconnect ed. Initialize the
system. ( P.205)
If this message contin ues to be displayed

■Sensor detection information
●The sensor's detection areas are limited
to the areas around the vehicle front and
rear bumpers.
●The following situations may occur
during use.
• Depending on the sh ape of the object
and other factors, the detection distance
may shorten, or detection may be impos-
sible.
• There will be a short delay between
object detection and di splay. Even at low
speeds, there is a possibility that the
object will come wi thin the sensor’s
detection areas befo re the display is
shown and the warning beep sounds.
• It might be difficult to hear the buzzer due
to the volume of the audio system or air
flow noise of the air conditioning system.
• It may be difficult to hear the buzzer if buzzers for other systems are sounding.
■Objects which the system may not be
properly detected
The shape of the object may prevent the
sensor from detecting it. Pay particular
attention to the following objects:
●Wires, fences, ropes, etc.
